Less than half a dozen of these are either typically desert animals or confined to deserts other than in this locality. Almost all groups of birds are equally well represented, and the marshes are often crowded with many kinds and many families. Ducks of a dozen species are plentiful, and there are many waders such as the stilts and avocets. Gulls and pelicans play a considerable part in the natural economy, as we shall see: and the number of crows, owls, swallows, swifts, goatsuckers, and birds of prey, plus the scavenging vultures, signify a large animal food supply. The rest of the roster of resident birds reads like a catalogue of the avian fauna of the Southwest generally, just about the only species not present being those most typical of the Sonoran Deserts. The reptiles, however, show more pronouncedly desert affiliations, led by the Desert Tortoise. There are twenty species of snakes including the Desert Gopher, the Sidewinder, and two other rattler
